Just wanted to show you all one of my UOA's from my 02 Cummins. I only had 3,500 miles on the oil because previously I did an Amsoil engine flush and wasn't sure how early I should change this oil after I did that flush. I'm pretty sure I used Supertech 15w-40 but can't completely remember. I have used that oil about 3 or 4 times in a row though and it's been great! Normally I do my oil changes at the 10k mile mark. Right now I'm using Mobile Delvac Extreme 15w-40 Synthetic and I'll be getting an analysis after 15k miles. Also looking into using Redline 15w-40 afterwards since it is a group V oil mixed with some group IV. Truck is at 426k miles right now.
